Fertilizer is typically transported on a vessel in bags or bulk form. Bagged fertilizer is handled in a similar manner to other bagged cargo, using a system of conveyor belts or elevators to load and unload the bags onto the ship. Bulk fertilizer is typically loaded and unloaded using specialized cargo handling equipment, such as cranes or pneumatic conveyor systems. To prevent the fertilizer from spoiling or deteriorating during the voyage, the cargo hold or deck must be kept cool and dry. Upon reaching the destination port, the fertilizer is unloaded using the same cargo handling equipment and transported to its final destination.
